Cesarean childbirth in sweden: Effects on the mother and father-infant relationship

The effects of Cesarean delivery on father-infant and mother-infant interaction were studied in a sample of 30 Swedish, two-parent families with a full-term healthy first-born infant. Fifteen infants were delivered vaginally, and 15 infants were delivered under full anesthesia by Cesarean section. The infants and parents were observed at home when the infants were 3 and 8 months old. The findings indicate that mothers of infants delivered by Cesarean section reacted less positively when they saw their infants for the first time and encountered more difficulties breastfeeding than did mothers of vaginally delivered infants. At 3 months post-partum, fathers of infants who were Cesarean-delivered participated in a greater amount of caregiving activities. There were no differences between Cesarean and vaginally delivered mothers at 3 months after delivery. At 8 months, there were no differences between the two groups (Cesarean and vaginal) on either the interview questions or on-any of the behavioral measures. Results from this study do not support reports from the USA of long-lasting effects of Cesarean delivery on parent-infant interaction. The results suggest the need to study cultural variations that surround Cesarean section delivery so as to understand in what way the subsequent parent-infant relationship is influenced by this event.     

A social systems perspective of adolescent pregnancy: Determinants of parent and parent-child behavior

Social systems theory was used as a framework for examining the relationships among demographic characteristics (age, education level, marital status, social class, income), intrapersonal beliefs (self-esteem, locus-of-control, and parent attitudes), social support, and pregnancy, birth-related, and postpartum outcomes. The subjects were 21 teenage mothers who participated in a model-demonstration program designed to provide and mediate support that would decrease stress and foster positive functioning during and after their pregnancies. The findings showed that social support, social class, and locus-of-control were related significantly to the subjects' personal well-being and family climate during the course of their pregnancies. Education level, social class, and social support significantly predicted both birth-related and postpartum outcomes. Participation in the demonstration project had positive influences on self-esteem, locus-of-control, and caregiver styles of interaction. The results are discussed in terms of the need for a broader-based, social systems perspective of the factors that influence positive outcomes among pregnant teenagers.     

A Comparison of Modern and Popular Approaches to Calculating Reliability for Dichotomously Scored Items

Recent work on reliability coefficients has largely focused on continuous items, including critiques of Cronbach’s alpha. Although two new model-based reliability coefficients have been proposed for dichotomous items (Dimitrov, 2003a,b; Green & Yang, 2009a), these approaches have yet to be compared to each other or other popular estimates of reliability such as omega, alpha, and the greatest lower bound. We seek computational improvements to one of these model-based reliability coefficients and, in addition, conduct initial Monte Carlo simulations to compare coefficients using dichotomous data. Our results suggest that such improvements to the model-based approach are warranted, while model-based approaches were generally superior.     

Cortisol reactivity and regulation associated with shame responding in early childhood

The purpose of this study was to characterize cortisol response and regulation associated with shame responding in early childhood and to examine how general the relation between shame and cortisol is. It was predicted that children responding to task failure with shame would show a larger and more prolonged cortisol response than other children. Participants were 214 children (124 boys, 90 girls) ranging from 3.7 to 4.5 years of age (M = 4.14 years, SD = 0.24). Shame responding was assessed from children's emotion-expressive behavior in response to failing 6 performance tasks, 2 preceding (initial) and 4 following (subsequent) assessment of hypothalamic-pituitary-adrenal axis activation. Cortisol response and regulation associated with failure were assessed from saliva sampled before and 15, 20, 25, 30, and 40 min following the first of the 2 initial failures. For boys and for some girls, high initial shame was associated with greater cortisol reactivity and slower regulation of the cortisol response. For boys, high initial shame and relatively slow regulation of the associated cortisol response predicted subsequent shame responding occurring after recovery of the cortisol response. For girls, high initial shame, but not cortisol response, predicted subsequent shame responding. (PsycINFO Database Record (c) 2008 APA, all rights reserved).     

Diabetes and psychological co-morbidity in children with a family history of early-onset type 2 diabetes

The present study was conducted to evaluate for depressive symptoms and undiagnosed diabetes in children with familial history of early-onset type 2 diabetes. Studies have shown that diabetes doubles the risk for depression and that the duration of diabetes is related to the severity of the depression. Individuals with depression are also said to be at greater risk for developing diabetes. In many cases diabetes is detected whilst screening for depression. Fifty-three children aged between 6 and 17 years were screened for diabetes and assessed for depressive symptoms using the Children Depression Rating Scale, revised version (CDRS-R). Thirty-six (68.0 %) of the children with a family history of early-onset type 2 diabetes had CDRS-R scores consistent with likely or very likely major depressive disorders. Depressive symptoms score was predicted best by the number of generations of diabetes in the family, with an associated r = .65 and adjusted R(2) = .41. As the generations of diabetes increased, the more likely it was for a child to have diabetes (r = .38, p = .005). Four (7.5%) of the children were diagnosed with diabetes. The findings suggest that depressive symptoms are common in children with a family history of early onset type 2 diabetes and may co-exist with diabetes. The independent variable that reliably predicted the child depressive symptoms score was the number of generations of diabetes in the family.     

Children's developing notions of (im)partiality

This research examines the development of children's understanding that people's judgments may be skewed by relationships, and that situational factors may make it difficult to be impartial. One hundred and seventy-one adults and children between kindergarten and eighth grade heard stories about judges in contests with objective or subjective criteria for winning. In Experiment 1, by fourth grade, children rated a judge with no personal connection (the "neutral judge") as being more likely to be objective than a judge with a personal connection (the "connected judge"). Younger children showed the opposite pattern. Experiment 2 replicated this finding for judges, and also found that children across development have similar ideas regarding the characteristics for being a good judge. Not until eighth grade, however, did children indicate that a connected judge was more problematic in subjective situations than in objective ones.     

Trust amply recompensed: psychological research at Weyburn, Saskatchewan, 1957-1961

During the 1950s and 1960s professionals intensely debated the prospect of changes in the mental health system, largely as a result of the introduction of new therapies, revised theories of mental disorder, and shifting policies governing mental health accommodation. As well as giving rise to new subspecialties within medicine, psychiatrists in some jurisdictions at this time worked closely with psychologists in an attempt to offer a more comprehensive set of options that merged theory with practice. In Saskatchewan, mental health professionals worked closely with government officials and bureaucrats and produced a variety of innovative strategies that addressed changing priorities in this system. This article examines the role played by psychologists in Saskatchewan during this period as they worked cooperatively with psychiatrists and bureaucrats to merge medical, psychological, and political perspectives in a system aimed at accommodating mental illness in the wake of new theories and treatments that questioned the efficacy of care in institutionalized settings in the wake of growing suggestions for care in the community.     

Explaining contradictory relations between risk perception and risk taking

Different studies have documented opposite relations between perceived risk and behavior. The present study tested a theoretical explanation that reconciles these conflicting results. Adolescents (N= 596) completed alternative measures of risk perception that differed in cue specificity and response format. As predicted by fuzzy-trace theory, measures that emphasized verbatim retrieval and quantitative processing produced positive correlations between perceived risk and risky behavior; risk perceptions reflected the extent to which adolescents engaged in risky behavior. In contrast, measures that assessed global, gist-based judgments of risk produced negative correlations; higher risk perceptions were associated with less risk taking, a protective rather than reflective relation. Endorsement of simple values and principles provided the greatest protection against risk taking. Results support a dual-processes interpretation of the relation between risk perception and risk taking according to which observed relations depend on whether the cues in questions trigger verbatim or gist processing.     

Measuring motivation multidimensionally: development of the Assessment of Individual Motives-Questionnaire (AIM-Q)

We report the development of the Assessment of Individual Motives-Questionnaire (AIM-Q), a new instrument based on an evolutionary psychology theory of human motivation. It provides multitrait-multimethod (MTMM) assessment of individual differences on 15 motive scales. A total heterogeneous sample of N = 1,251 participated in eight studies that evaluated the homogeneity, internal consistency, test-retest reliability, and MTMM convergent and discriminant validities of the AIM-Q's three methods. These studies generally support the overall strategy of assessing individual differences in multiple evolutionary-based motives with multiple methods. Additional validity studies are underway and, when validated further, the AIM-Q may offer a promising option for evolutionary psychologists and behavioral geneticists wanting to incorporate individual differences into their research but have had to use existing self-report measures of personality, which were not designed for such a purpose. It may also offer clinical and counseling psychologists an additional approach to personality measures for the prediction of behavior.     

In Defense of a Non-Causal Account of Reasons Explanations

This paper defends my claim in earlier work that certain non-causal conditions are sufficient for the truth of some reasons explanations of actions, against the critique of this claim given by Randolph Clarke in his book, Libertarian Accounts of Free Will.
